* ArcFatigue: The whole "betrayal" thing with the Gun-Swordsmen got stretched out way, way too long. It wouldn't be so bad if we got to see Melan and his friends finally get over this and act like the team they're supposed to be for more than one scene. It would have been even ''better'' if they actually got to fight the FinalBattle.
* EsotericHappyEnding:
** ''If'' you think that [[spoiler: Marin goes to Brigadoon with Melan]] at the end, that's a truly strange ending. What kind of future can there be for [[spoiler: a thirteen-year-old human and an alien robot?]]
** The other way around, while better in practical terms, is just as sad, seeing as they most likely [[spoiler: never see each other again.]]
** Not to mention the fact that some of the villains [[spoiler: namely Kuston and Lulu/Aloma]] are still alive and could potentially still cause some problems.
* FauxSymbolism:
** We have a global catastrophe that threatens to wipe out the human race, giant ships called Arks, and rainbows as symbols of hope. [[TheGreatFlood Does this sound familiar?]]
** There's also Creis, whose name, duty, and powers are almost identical to those of [[MessianicArchetype Christ]], and the Day of Pasca, which shares many similarities with the resurrection story behind Easter (and believe it or not, Easter is called Pascha in Greek).
* IronWoobie: Melan endures all kinds of punishment without complaint.
%%* {{Moe}}: [[IncrediblyLamePun "Moe is moe moe!"]]
* SoBadItsGood: The English dub. The voice acting is adequate but hilarious.
* {{Squick}}:
** Most disconcertingly, Marin (a 13-year-old girl)'s frequent panty shots and nude scenes, along with the episode where Moe magically turns into a naked giant.
** Marin's relationship to Melan can be read as this as well, since their relationship gradually changes from LadyAndKnight to an explicitly romantic one, and Melan is designed and written as an adult man.
* SubbingVersusDubbing: The Japanese voice cast has better chemistry than the English dub that was cast well but doesn't leave as much of an imprint as the original.
* TheUntwist:
** The true identity of the BigBad might come as a shock to some or a disappointing anticlimax to others.
** [[spoiler: Aloma and Lulu]]'s similarities are so painfully obvious; they couldn't possibly be the same person. Nor could [[spoiler: Lulu]] be behind Brigadoon's troubles. But he is.
** There's so much of this in the final episode that it's ridiculous. First we have [[spoiler: Chroma showing up with a new batch of Reikons just in time.]] Then there's also the fact that Marin turns out to be [[spoiler: stronger than Creis Marine, allowing her to be TheChosenOne after all.]] And then out of nowhere, Aloma gives TheReveal that [[spoiler: Marin is Creis Marine's prototype and thus her ancestor, but it doesn't answer any questions about Marin's true origins.]]
* ValuesDissonance: There's a lot of underage female nudity, either in light-hearted or dramatic scenes.
* WhatDoYouMeanItsForKids: See the {{Squick}} examples, plus OverdrawnAtTheBloodBank, HumansAreTheRealMonsters, KidsAreCruel, and SlidingScaleOfIdealismVersusCynicism.
* {{Woobie}}:
** Marin. [[spoiler: She suffers so much due to circumstances outside of her control it's impossible not to feel sympathy for her.]]
** Moe qualifies for this as well, especially when [[spoiler: she's the victim of a Monomakia that causes her to uncontrollably grow bigger until she is in danger of exploding]].
** Melan counts, too, though in his case he's more of an IronWoobie.
